Snakes in the City handler Harley Jones who was called in by police to help says he was pleasantly surprised to see the large crowd that had gathered around the snake were more curious than fearful.

"I think one of the positive things, there was a fairly large people around it - the police were there - it was the end of lunch time and everyone was very curious," Mr Jones told AAP on Wednesday.

He praised the pub manager for fast thinking by putting a cover over the snake to calm it down.

Mr Jones said the snake had red bloody foam near its mouth, which suggested it had internal injuries.

He took the snake to the vet but said he was advised on Wednesday morning that it died.

Mr Jones said it's not the first time he's had to rescue a snake from the CBD but they are normally escaped pets.

However this time was the first time he had seen the highly venomous species, saying it was likely the reptile had hitched a lift into the city in a car, potentially in an engine bay, before falling out.
